Assertion (A): | The stream of water flowing at high speed from a garden hose, and pipe tends to spread like a fountain when held vertically up but tends to narrow down when held vertically down. |
Reason (R): | In any steady flow of an incompressible fluid, the volume flow rate of the fluid remains constant. |
1. | Both (A) and (R) are True and (R) is the correct explanation of (A). |
2. | Both (A) and (R) are True but (R) is not the correct explanation of (A). |
3. | (A) is True but (R) is False. |
4. | Both (A) and (R) are False. |
Assertion (A): | The equation of continuity is \(A_{1}v_{1}\rho_1=\)\(A_{2}v_{2}\rho_2\) (symbols have their usual meanings). |
Reason (R): | The equation of continuity is valid only for incompressible liquids. |
1. | Both (A) and (R) are True and (R) is the correct explanation of (A). |
2. | Both (A) and (R) are True but (R) is not the correct explanation of (A). |
3. | (A) is True but (R) is False. |
4. | Both (A) and (R) are False. |
